How do two-way solenoid valves work in hydraulic systems?

Electromagnetic coil activation controls fluid passage through the inlet and outlet ports. Magnetic field shifts the internal mechanism when energized, opening or closing the flow path based on the valve’s normal configuration.

What’s the difference between normally closed and normally open solenoid valves?

Normally closed 2-way solenoid valves block flow when de-energized, and open when powered, providing fail-safe operation. Normally open valves allow continuous flow until energized to close. Choose based on whether you need a constant flow or a safety shutoff.

Should I choose brass or stainless steel construction?

Budget definitely matters here. Brass machines are easier and less costly for moderate-pressure jobs that do not involve corrosive fluids. Steel costs more upfront but lasts longer in harsh conditions. Chemical plants, marine environments, and similar scenarios? Go steel every time.

When should I select direct-acting versus pilot-operated designs?

Direct-acting units are quick and work without a pressure differential, but they’re power hungry. Pilot-operated 2-way solenoid valves move bigger volumes at higher pressures. The trade-off? They need minimal pressure to operate correctly.

What industries commonly use two-way solenoid valves?

All over manufacturing – automation lines, oil rigs, water plants, HVAC setups, and more. Pneumatics use tons of them. Irrigation systems, plumbing applications, and basically anywhere electrical control beats manual valve operation.

Product Details & Applications

Our inventory covers direct-acting and pilot-operated designs, each built for different jobs. Direct-acting models? Great for smaller diameter work where speed matters – think instrumentation, medical devices, portable welding rigs. Pilot-operated versions handle larger flows and higher pressures, making them ideal for industrial automation.

Normally closed 2-way solenoid valves stay sealed until you power them up (fail-safe operation), while normally open designs keep flowing until actively shut off. Material choice is crucial here – brass gives you cost-effectiveness for moderate conditions. Stainless steel offers superior corrosion resistance in harsh environments and when working with more challenging substances.
